Modern Defense: Two Knights Variation, Suttles Variation
This opening arises after the moves 1. e4 g6 2. d4 Bg7 3. Nc3 c6 4. Nf3 d6. It is a flexible and somewhat hypermodern setup where Black delays immediate confrontation in the center, instead focusing on solid development and preparing to challenge White's central control later.
Characteristic: Black’s move 3...c6 is the hallmark of the Suttles Variation. It supports the d5 square and prepares for a possible ...b5 or ...d5 push, aiming to undermine White’s center from a solid and resilient position.
Strategy: From Black’s perspective, this line is primarily defensive and positional, seeking to counterattack rather than directly seize the center early. White, on the other hand, has the opportunity to build a strong pawn presence in the center with pawns on e4 and d4, thus playing more aggressively.
Center Control: White aggressively occupies the center with pawns on e4 and d4, while Black adopts a hypermodern approach, allowing White initial central space but planning to challenge and attack it later with moves like ...c6 and ...d6 supporting ...e5 or ...d5 breaks.
